Description

TECHNICAL FIELD

[0002] As an important building and decoration material, ceramic tiles usually need to be glazed to improve their aesthetic appearance, stain resistance and durability. In the traditional glazing process, a conveying belt is usually used to continuously convey the ceramic tiles, and a fixed or movable spray head is used for glaze spraying. However, this method has obvious limitations in actual production. On the one hand, the ceramic tiles may be slightly displaced or vibrated due to mechanical vibration, speed fluctuation or uneven belt tension during the operation of the conveying belt, which affects the uniformity and consistency of the glazing, and problems such as uneven glaze thickness, edge missing spraying or glaze accumulation may occur. On the other hand, the traditional clamping or positioning method relies on manual or simple mechanical fixation, and it is difficult to achieve rapid, accurate and stable clamping and release of the ceramic tiles in high-speed continuous operation, especially in the production of large-size or thin ceramic tiles. The unstable clamping may cause the ceramic tiles to be damaged or displaced, further reducing the production yield and efficiency.

[0003] In addition, the existing spraying equipment often lacks a mechanism for dynamically and stably holding the ceramic tiles during spraying. The ceramic tiles are in a "free" or "semi-fixed" state during conveying and spraying, and it is difficult to completely isolate the influence of external vibration and transmission errors. Although some individual solutions attempt to use pneumatic or electric clamps with independent drive mechanisms to achieve the grabbing and moving of the ceramic tiles, the structure is complex, the cost is high, and the coordination and reliability of the clamping and release actions are still insufficient, especially in the cyclic operation, it is difficult to achieve efficient and continuous clamping-spraying-release automation process.

[0004] Therefore, there is an urgent need for a glaze spraying process and equipment that can achieve stable clamping, accurate positioning and automatic release during the conveying and spraying of ceramic tiles, to overcome the problems of uneven glaze, low production efficiency and other problems caused by vibration, inaccurate positioning and unreliable clamping in the prior art, so as to meet the needs of large-scale production of high-quality ceramic tiles.

[0015] A spraying process of a ceramic tile glaze spraying device, comprising the following steps:

[0016] Step one, feeding and clamping: start the first conveying belt to convey the ceramic tile to be sprayed to the fixed position at one end of the base; at the same time, start the motor to drive the threaded rod to rotate, thereby driving the U-shaped frame and the first spur gear to move towards the ceramic tile; the first spur gear is in mesh with the first gear slot on the side plate and the movable seat, thereby driving the two movable seats to move synchronously towards the two sides of the ceramic tile along the T-shaped plate; when the movable seats move to the two sides of the ceramic tile, the top end of the vertical rod contacts and is pressed down by the fixed frame, the clamping block is pulled by the connecting rod to disengage from the ratchet wheel, the torsional spring releases the torque, the second spur gear and the rotating rod are driven to rotate, the rotating plate drives the rubber block to turn outwards, and the ceramic tile is clamped on both sides.

[0017] Step two, spraying and moving: after clamping, the motor is reversed to drive the movable seat to move the ceramic tile at a constant speed towards the second conveying belt; during the movement, the spray head sprays the glaze evenly downwards to complete the spraying of the surface of the ceramic tile; at this time, the clamping block is re-engaged into the ratchet wheel under the action of the spring to lock the position of the rotating plate, thereby preventing the ceramic tile from loosening during the movement.

[0018] Step three, unloading and resetting: when the front end of the ceramic tile moves above the second conveying belt, the bottom end of the vertical rod disengages from the surface of the base, and then the displacement plate contacts and is pushed to slide inwards, thereby driving the second spur gear to rotate through the second gear slot, so that the rotating plate is turned back into the rotating groove, and the rubber block is separated from the ceramic tile; the ceramic tile falls onto the second conveying belt and is sent away; the movable seat continues to move to reset, thereby preparing for the clamping and spraying cycle of the next ceramic tile.

[0019] Compared with the prior art, the present application has the following advantages:

[0020] 1. The ceramic tile is stably clamped and accurately positioned during the whole spraying process.

[0021] The application makes the ceramic tile in the clamping state of the movable seat in the whole process of receiving from the first conveying belt, spraying and transferring to the second conveying belt through the cooperation of the moving mechanism and the clamping mechanism. The clamping mechanism adopts the linkage design of ratchet block-torsional spring, cooperates with the contact triggering mechanism of the vertical rod and the fixed frame and the base, realizes the automatic execution and locking of the clamping action, effectively avoids the displacement of the ceramic tile caused by the vibration of the traditional conveying belt, ensures the high stability of the position of the ceramic tile in the glazing process, and significantly improves the uniformity of the glaze and the completeness of the edge coverage.

[0022] 2. The automation degree and production continuity of the spraying operation are improved.

[0023] The device realizes the reciprocating movement of the movable seat on the T-shaped guide rail through the transmission system of the motor, threaded rod, U-shaped frame and first straight gear, and forms the full-automatic circulation process of "feeding-clamping-transferring-spraying-releasing-resetting" in combination with the automatic clamping and releasing functions of the clamping mechanism. The efficient and continuous processing of the ceramic tile can be realized without manual intervention, the labor intensity is greatly reduced, and the production rhythm and equipment utilization rate are improved.

[0024] 3. The reliability and self-adaptive ability of the clamping mechanism are enhanced.

[0025] The cooperation design of the rotating plate and the rubber block in the clamping mechanism can adapt to the clamping requirements of ceramic tiles with different thicknesses. The rubber material provides sufficient clamping force and avoids damage to the tile surface. The locking mechanism of the ratchet and the block ensures that the clamping state is irreversible during the transferring process, preventing the ceramic tile from loosening or falling off during movement. The trigger release design of the vertical rod and the displacement plate ensures that the ceramic tile can be smoothly and automatically released when it reaches the second conveying belt, avoiding jamming or collision and improving the reliability of system operation.

[0026] 4. The structure is compact, stable in operation and easy to integrate into the existing production line.

[0027] The overall structure of the device is based on the modular design of the base, side plate, cross plate and the like. The moving mechanism and the clamping mechanism are integrated in a limited space, the layout is reasonable, and the movement trajectory is clear. The sliding cooperation of the T-shaped guide rail and the movable seat ensures the stability of movement, and the motor-threaded rod transmission mode has high control precision and fast response. At the same time, the first conveying belt and the second conveying belt can be connected to the existing conveying system of the production line, which is convenient for implementation and integration, has good engineering applicability and popularization value.

[0028] In summary, the application optimizes the positioning, clamping and transferring mode of the ceramic tile in the spraying process in a systematic way, effectively solves the problems of uneven glaze and low production efficiency caused by vibration and unstable clamping in the traditional process, realizes the high-uniformity, high-automation and high-reliability ceramic glaze spraying production, and has obvious technical advancement and practical benefits.

8. A spraying process of a tile enamel spraying apparatus according to any one of claims 1 to 7, characterized in that, Includes the following steps: Step 1, Loading and Clamping: Start the first conveyor belt (2) to transport the tile to be sprayed to a fixed position at one end of the base (1); at the same time, start the motor (704) to drive the threaded rod (705) to rotate, which will drive the U-shaped frame (706) and the first spur gear (707) to move towards the tile; the first spur gear (707) meshes with the first tooth groove on the side plate (4) and the movable seat (701), which will drive the movable seats (701) on both sides to move towards the sides of the tile along the T-shaped plate (702); when the movable seats (701) move to the sides of the tile, the top of the vertical rod (811) contacts the fixed frame (801) and is pressed down, which will pull the clamp (808) to disengage from the ratchet (807) through the connecting rod (810), and the torsion spring (813) will release the torque, which will drive the second spur gear (812) and the rotating rod (806) to rotate, so that the rotating plate (805) will drive the rubber block (804) to flip outward and clamp the sides of the tile; Step 2, Spraying and Transfer: After clamping, the motor (704) reverses and drives the movable seat (701) to move the tile at a constant speed toward the second conveyor belt (3); during the movement, the nozzle (6) sprays glaze downwards evenly to complete the tile surface spraying; at this time, the locking block (808) is re-engaged into the ratchet (807) under the action of the spring (809), locking the position of the rotating plate (805) to prevent the tile from loosening during the movement; Step 3, Unloading and Resetting: When the front end of the tile moves above the second conveyor belt (3), the bottom end of the vertical rod (811) detaches from the surface of the base (1). Then the displacement plate (814) contacts the fixed plate (802) and is pushed to slide inward. The second spur gear (812) is driven to rotate through the second tooth groove, so that the rotating plate (805) rotates back into the rotating groove (815), and the rubber block (804) separates from the tile. The tile falls onto the second conveyor belt (3) and is sent away. The movable seat (701) continues to reset and move, ready to perform the clamping and spraying cycle of the next tile.
